' l This invention relates to beverage dispensing devices and. has for an object to provlde means for carbonating a liquld during its passage through and at the moment. of With- 6 drawal yfrom a dispensing faucet.v A further` object is to provide means forcontrolling the flow of liquid and carbonio acid gas in proportionate ratio through a. vfaucet where by one operation of the faucet lever l a drink may be drawn in which the proper Vamount of carbonating gas is mixed. 'A

In the annexed drawings forming a part of this specification; v Fig? 1 is a'vertical section through a porl tion of the container and the outlet conduit and faucet. v

Fig. 2 is an enlarged horizontal section taken on line 2'-2 of Fig. 1.

Fig. 3 is a vertical section taken on line i 1'. Fig. 4 isgia vertical section taken online '4-4ofFig.1. l

As shown in the drawings,. the beverage container .is mounted within an ice recepof the container wall'l and'receptacle wa 2 being shown in Fig. 1. The outlet conduit through which the beverage is dispensed has an elbow fitting 3 within the container Wall 1 ,to I0 which is connected adownwardly-extendin inlet pipe 4. The beverage flows ,upwardly under pressure throuo'h this pipe a into lit- 3. A horizontalD threaded pipe-section 5a Vin 5 also carries a nut 11 between a 'packin .'oint.

Masher 13 to make a fluid-tight T e r'ear wall of the elbow fitting 3 I'1s extendedl or thickened to provide a threaded socket 14 adaptedfwto 'receive the threaded end of .a tubel lfsomewhat smaller than the internal diameter of tube-5 and extendin -axia'lly therein .to the front end thereo Communicating with the rear end vofthe' socket 14 through the upper side thereof is a conduit 16 leading to a suitable supplyjof carbonio-acid gas. Insetting up' of the valve stem 35 1mg a s101540 therein `in 110 shouldered inner louter end of the stem 2 5 g head 26 and. serves to normally hold the lvalve head 24 seated on the end of nipple 20.

an integral head 6 engaging the outer si e of the'wall 2, extends through drawn snugly against ipe section which and the wall 2Ois clamped a metal Washer 12 and -ffof the head andan 'fins 39u engagin the apparatus the tube 15 can be screwed back, in the socket 14 to partially cut oil' the inlet passage from the conduit 16, as for instance,y when the device is used for dispensing beverage requiring less gas. .A The cuter end portion 17k of the innerA gas tube 15 is bored to ,a greater internal diameter providing an internal vshoulder 18 at the inner end of the portion 17. The outer end of tlm tube l5 is also internally threaded. to receive a zthreaded plug 19 which has a. end and an axial nipple 20. Surrounding the nipp1e20 and clamped between the shoulder 18'and the end shoulder` on the plug 19 around the nipple isa packing Washer 2l. The plug 19 has an' axial passage therethrough consisting of a large .bore 22 extending to adjacent the shouldered inner end and a small bore 23 through the nipple 20. A valve head 24 within the tube .15 at the inner end of the plug 19 has screwed thereon a' stem 25 extending forwardly through the plug 19,' and the has a hexagonal head 26 which has a sliding fitin the bore 22 ofthe plug 19. A compression coil spring 27 surrounding the stem 25 is interposed bei tween the internal shoulder at the inner end of the' bore 22 and the enlarged hexavonal A suitable packing 28 is provided on the face of the valve head to effectively seal the opening. f 'Y A faucet-bod 29- havingl a.' bore of the same internal iameter as the pi 5 is screwed into the head 6 thereof andma sep- 'arate spout 30 is secured upon the outer end of the body 29 b means of 'a coupling nt 31.. The inner en of the spout 304 hasa valve a Vvalvehead 33 iitsand this valve head 33 Y Y has a' peripheral flange 34 at its rear end secured to the threaded end of a stem 35 by means of acouplin' .collar 36 which has an inturned ange 37 tting over the flange internal thread. engaging the enlarged threaded end of the stern- 35. The c'ollar436 hasradial-external lribs 38 engaging the interior of the faucet body 29 and .the rear end of vthe-stem 35u has radial the interior ofthe faucet body29, these ri s andns '39 serving to-center and guide the valve .33. The main body e5 .seat 32 against which the rounded end of the beverage.

which the lower rounded end of a lever arm 4l `fits. Lever arm 41 extends` into a recess 42 formed in the" uppeir`v wall of the faucet body 29 and has an apertured end tting over the flattened inner end of a transversely-extending shaft 43, the outer end of which is fixed to one leg 44 of a forked lever 45. The opposite leg 46 of the lever 45 is ypivoted on the round head of a? screw 47 outside a spacing washer 48 held in place by the screw 47 which is secured in the faucet body 29 in axlal alinement with the shaft 43.

When the valve head 33 is in engagement with the seat 32 the rear end of the stem 35 is spaced slightly apart from the head 26 of the gas-valve stem 27. When the faucet lever 45 is swung forwardly the valve head 33 is moved away from its seat 32 permitting liquid toiow into the spout 30. A further movement to the lever 45 in the same direction brings the rear end of the liquid valve stem 35 into engagement with the head y26 lmoving the gas valve head 24 rearwardly in opposition to the spring 27,*thereby permitting carbonio-acid gas to be injected into the liquid flowing through the faucet. By varying and timing the forward pull on the lever 45 the amount of carbonic gas injected into the liquid may be regulated. As a. result the beverage dispensed is always live and elervescent at the moment of withdrawal and there is no time lost or wasted in dispensing a full glassvof the beverage, especially with carbonated syrupy mixtures which foam excessively when released and which heretofore have been dispensed in large glasses or mugs in which the beverage is allowed to settle before drinking with obvious losses of carbonio gas during the settling process. On the contrary the device ills a glass quickly and fully without excessive foam and with a full charge o f carbonio-acid gas, making a ready and palatable ei'ervescent drink immediately as withdrawn. Y
